IRL consent is always hot. In fiction sometimes noncon is hot too but this album is all about consent. Mostly focused on BDSM and/or rougher sex.
Sometimes there's mild dubcon e.g. the uke wants it but he's too shy so the seme has to be pushy, or he starts saying "stop" but only because he's about to come or he's overstimulated not because he really wants to stop, etc.
Sexy scenes from many different manga that are also sweet and cute. Mutual enjoyment. No rape or "I'm forcing you because we love each other/to demonstrate my feelings (but I know you can't physically fight back)" BS.
